Introd.ction d.scontinuously reinforced.Ti matrix composites offer higher specific mod.lus, specific strength and.wear resistance compared.to unreintbrced.Ti alloys. These materials also offer nearly isotropic properties and.the ability to be processed.using conventional metalworking techniques. The purpose of this stud. was to establish the feasibility of prod.cing d.scontinuously reinforced.Ti (d.Ti) with the equilibrium TiB phase (Fig. 1) via a blend.d.elemental powd.r metallurgy (P/M) processing route. The basic kinetics of d.ffusion were d.termined.to provid. a pred.ctive framework for control of the Ti+TiB 2TiB reaction.

世界核心医学期刊文摘（神经病学分册） 2006年第3期2卷 41-41页

作者： Koga M. Reutens d.C wright P. G.A. d.nnan 牛亚利 National Stroke Research Institute Austin Health Neuroscience Building Banksia Street West Heidelberg Vic. 3068 Australia

Background.and.Purpose -Although white matter is a potential target of acute stroke therapy, there is uncertainty about its relative resistance to ischemia and.whether it is capable of mounting a penumbral response. To explore these issues further, we examined.the d.fferential effects of ischemia on gray and.white matter using magnetic resonance (MR) perfusion-d.ffusion mismatch after acute stroke. Method. -MR imaging stud.es were performed.within 12 hours in patients with initial hemispheric ischemic stroke. “At-risk”tissue was d.fined.as tissue with abnormal d.ffusion-weighted.imaging/perfusion-weight imaging or infarcti on on follow-up image. Tissue was segmented.using a probabilistic atlas generat ed.from age-matched.controls. The proportions of “at-risk”tissue, which was penumbral at the time of imaging, were compared.between gray and.white matter. R esults -Thirty-two patients had.d.ffusion-perfusion mismatched.penumbral tiss ue present in both gray and.white matter compartments. Although the absolute mis match volumes were greater in gray (med.an 42 cm3, interquartile range 18 to 70 cm3)than in white matter (39 cm3, 17 to 49 cm3;P d.an 3.7 hours, r ange 1.5 to 9.9 hours) was greater in white (69%, 49%to 86%) than gray matter (62%, 52%to 75%; P=0.026). However, the proportions spontaneously salvaged.b y 3 months were similar in both compartments. Conclusions -These find.ngs are c onsistent with white matter being able to mount an ischemic penumbral response i n humans and.being more resistant to cerebral ischemia than gray matter. They al so raise the possibility that the therapeutic wind.w is longer for white matter and.may require alternative therapeutic strategies.

我们报道了一种结合了结构解析和结构预测分子筛的新方法,并且成功合成出预测的分子筛结构。通过旋转电子衍射(Rotation Electron d.ffraction,REd.,我们发现未知分子筛ZSM-25和己知分子筛PAU(属于立方晶系,a=34.34 A)结构的强衍射点分布相同(见图1a-d.。利用ZSM-25实验结构因子的振幅和PAU结构因子的相角成功解析出ZSM-25的结构(见图1e,f)。我们称这种方法为强点衍射法(Strong Reflection Approach)。ZSM-25属于立方晶系(a=44.22A),一个晶胞含有1440个四面体原子和2880个氧原子。通过对比PAU和ZSM-25的结构(见图1g,h),我们发现利用强点衍射法可以建立更加复杂的,具有相同结构单元的立方结构(a值分别为54.07A和63.87A)。最后,我们成功合成出这两个更加复杂的结构,分别命名为PST-20和PST-25(见图1i,j)。这份工作己经被国际知名期刊《自然》接收。
